Poker is a card game in which players make bets into a central pot based on the strength of their hand. A player can win the entire pot by having a high-ranking hand or by bluffing. While luck plays a large role in the game, skill and psychology also have an impact.
The game is played with a standard deck of 52 cards, which are dealt to each player in rotation. A button (usually a white plastic disk) is used to indicate a nominal dealer, and the right to deal passes clockwise around the table after each round of betting. A dealer shuffles the pack, offers it to the player to their right for a cut, and then deals the cards one at a time.
Once the initial hand has been dealt, each player can decide to fold, call or raise a bet. In most games, betting is done in a clockwise direction and the highest-ranked hand wins the entire pot.
To make a hand, the player must use their own two personal cards in conjunction with five community cards on the table. A full house consists of three matching cards of one rank and two matching cards of another, while a flush consists of 5 consecutive cards of the same suit. A straight is made up of 5 cards that skip in rank but are all from the same suit, and a pair is 2 matching cards of any rank.
